With reference to FIG. 1, a communications system 10 including a mobilewireless communications device 12 according to the present disclosure isnow described. Although the communications system 10 is described withreference to one mobile wireless communications device 12, it should bereadily understood that there may be any number of mobile wirelesscommunications devices belonging to the communications system.

The communications system 10 includes an application server 18 whichcomprises a processor 20 and a memory 19 cooperating therewith forstoring a plurality of applications. The plurality of applications mayinclude any applications for the mobile wireless communications device12, for example games, or map applications.

The mobile wireless communications device 12 comprises a processor 16coupled to a memory 13, a wireless transceiver 14, an input device 15,and a display 17. The memory may be volatile memory, such as RAM, ornon-volatile memory, such as flash RAM or a hard drive. The input device15 may be a keyboard, a thumbwheel, or a trackball, for example. Theinput device 15 may also be a microphone or a wireless receiver (e.g.bluetooth), as will be appreciated by those of skill in the art. Ofcourse, the display 17 may be a touch sensitive screen and may thereforealso serve as the input device 15. In addition, the mobile wirelesscommunications device 12 may include a portable housing and arechargeable battery.

The processor 16 cooperates with the memory 13 and the wirelesstransceiver 14 for communicating with an intermediate server 22 via awireless network 11, that may typically be provided by a cellulartelephone network, but any suitable network (for example, WiFi) may beused. The network may be a Code Division Multiple Access (CDMA) network,a 3G network, or other suitable cellular network. Such a cellularnetwork provides for data transfer communications in addition to voicecommunications, and provides connectivity with the Internet.

The intermediate server 22 comprises a processor 24 cooperating with amemory 25 and a transceiver 23 for communicating with the applicationserver 18. This communication may be via the Internet. The processor 24,and a memory 25 of the intermediate server 22 are also for obtainingrespective current version information for associated current versionsof the plurality of applications. That is, the intermediate server 22learns the versions of the applications stored on the application server18. The intermediate server 22 may obtain this current versioninformation by polling the application server 22, or the applicationserver may send it to the intermediate server without a requesttherefrom, for example via a server push. Alternatively or additionally,the current version information may be sent to the intermediate server22 from an outside source (i.e. an administrator).

The processor 24 and memory 25 of the intermediate server 22 furtherobtain stored user application version information from the mobilewireless communications device 12. That is, the intermediate server 22learns the version of at least one application stored on the mobilewireless communications device 12. The intermediate server 22 may obtainthe stored user application version from the mobile wirelesscommunications device 12 by polling it, or the mobile wirelesscommunications device may send the stored user application version tothe intermediate server without a request therefrom, for example via aserver push.

The processor 24 and the memory 25 of the intermediate server 22cooperate to compare the stored user application version with thecurrent version information for the at least one stored userapplication. If the comparison shows that the stored user application(on the mobile wireless communications device 12) is an older versionthan the corresponding application stored on the application server 18,the intermediate server 22 downloads, via the transceiver 33, newapplication portions from the corresponding application stored on theapplication server 18. Before the intermediate server 22 downloads thenew application portions, it compares the application stored on themobile wireless communications device 12 with the correspondingapplication stored on the application server 18.

Referring now to FIG. 2A, this comparison is now explained. Theapplication stored on the mobile wireless communications device 12 hasportions A, B, and C. The corresponding application stored on theapplication server 18 is a newer version of the application and includesportions A, B, C, D, and E. The intermediate server 18 downloadsapplication portions D and E, as they are new application portions notincluded in the version of the application stored on the mobile wirelesscommunications device 12.

After the intermediate server 18 downloads the new application portions,it sends them, via the transceiver 23, to the mobile wirelesscommunications device 12 (which downloads them via its transceiver 14)to thereby update the mobile wireless communications device. Theprocessor 16 and memory 13 of the mobile wireless communications device12 cooperate to install the new application portions. As shown in FIG.2B, new application portions D and E have been added to the applicationstored on the mobile wireless communications device 12 (D and E areshaded to show they have been added).

Another example of the comparing and updating is now described withreference to FIGS. 3A and 3B. In FIG. 3A, the application stored on themobile wireless communications device 12 has portions A, B, and C. Thecorresponding application stored on the application server 18 is a newerversion of the application and includes application portions A, C, D, E,and F. Thus, application portions D, E, and F are new, while portion Bhas been removed. The intermediate server 18 downloads applicationportions D, E, and F as they are the new application portions notincluded in the version of the application stored on the mobile wirelesscommunications device 12. Further, the intermediate server 22 recordsthat portion B has been removed from the newer version of theapplication.

The processor 16 and memory 13 of the mobile wireless communicationsdevice 12 cooperate to install the new application portions and toremove the application portions no longer contained in the newer versionof the application. As shown in FIG. 3B, the new application portions D,E, and F have been added to the application stored on the mobilewireless communications device 12 (D, E, and F are shaded to show theyhave been added), while application portion B has been removed(indicated with an X).

Those skilled in the art will appreciate that the processor 16 andmemory 13 of the mobile wireless communications device 12 may cooperateto install the new application portions based upon user input (approvalfrom the user to install the new application portions) or based upon nouser input. In some instances, the mobile wireless communications device12 may accept user input of which applications may have new applicationportions installed therefore without user input, and of whichapplications may have the new application portions installed based uponuser input or approval.

In the embodiment schematically illustrated in FIG. 1, the intermediateserver 22 updates the mobile wireless communications device by sendingthe new application portions to the mobile wireless communicationsdevice 12 without a request therefrom, for example using a server push.Of course, in other embodiments, the mobile wireless communicationsdevice 12 may instead poll the intermediate server 22 for the newapplication portions.

In addition, in the illustrated embodiment, the mobile wirelesscommunications device 12 selectively sends the stored applicationversion information to the intermediate server 22. The mobile wirelesscommunications device 12 may accept user selection of which storedapplication version information about which stored user application maybe sent to the intermediate server 22. Therefore, the user mayadvantageously choose which applications he/she would like theintermediate server 22 to update as a matter of course.

In addition to updating applications already stored in the memory 13 ofthe mobile wireless communications device 12, the intermediate server 22may send notification of new applications thereto based upon at leastone selection preference. The selection preference may be a userselection of an application type, application name, applicationdeveloper, features supported by an application (i.e. touch screeninput, device orientation sensor input from a mobile wirelesscommunications device so equipped, etc), or other suitable selectionpreference. For example, a user may wish to be notified of any gamereleases related to a certain movie, or related to a political election.

This functionality of the mobile wireless communications device 12 isnow described with additional reference to FIG. 4. Here, the display 17of the mobile wireless communications device 12 is displaying a list ofapplication categories to the user. The user has selected that he/shewould like to receive notification of the availability of new card &casino games, as indicated by the check mark in the box next to thatcategory. This selection preference has been sent from the mobilewireless communications device 12 to the intermediate server 22.

With further reference to FIG. 1, the intermediate server 22 sendsnotification of availability of at least one new application to themobile wireless communications device 12 based upon the at least oneselection preference, without a request therefrom. For example, thisnotification may be sent via a server push, but in other embodiments,the mobile wireless communications device 12 may instead query theintermediate server 22 for availability of the at least one newapplication.

Shown in FIG. 5 is the notification received by the mobile wirelesscommunications device 12 and displayed on the display 17 thereof. Here,the mobile wireless communications device 12 has received and isdisplaying notification of the availability of ABC Solitaire, XYZ Poker,and QQQ Black Jack. The user may now select at least one of theapplications to download and install. The download may be directly fromthe application server 18 or may instead be from the intermediate server22. In some applications, the application server 18 or the intermediateserver 22 may send the new applications to the mobile wirelesscommunications device 12 without a request therefrom, for example via aserver push.

Those skilled in the art will understand that the application server 18and the intermediate server 22 need not be separate entities. Indeed,such an alternative embodiment of the communications system 10′ is nowdescribed with reference to FIG. 7. In this embodiment, the applicationserver 18′ comprises an application module 40′ to store the plurality ofapplications and an intermediate module 41′. The application module 40′and the intermediate module 41′ perform the same functions as theapplication server 18 and intermediate server 22, respectively, asdescribed above. As such, no further description of the applicationmodule 40′ and intermediate module 41′ is required, although it shouldbe noted that the application module and intermediate module maycomprise computer executable instructions that are stored in the memory19′ of the application server 18′ and executed by the processor 20′ ofthe application server.

A method of operating an intermediate server in accordance with thepresent disclosure is now described with reference to flowchart 30 ofFIG. 6. After the start (Block 31), at Block 32, respective currentversion information is obtained from an application server forassociated current versions of a plurality of applications storedthereon. At Block 33, stored application version information is obtainedfrom at least one mobile wireless communications device for at least oneapplication stored thereon.

At Block 34, the stored application version information is compared withthe current version information for the at least one stored application.At Block 35, new application portions are downloaded from a currentapplication associated with the current version information. At Block36, the new application portions are sent to the at least one mobilewireless communications device. Block 37 indicates the end of themethod.

Exemplary components of a hand-held mobile wireless communicationsdevice 1000 that may be used in accordance with the present disclosureare further described in the example below with reference to FIG. 8. Thedevice 1000 illustratively includes a housing 1200, a keypad 1400 and anoutput device 1600. The output device shown is a display 1600, which maycomprise a full graphic LCD. In some embodiments, display 1600 maycomprise a touch-sensitive input and output device. Other types ofoutput devices may alternatively be utilized. A processing device 1800is contained within the housing 1200 and is coupled between the keypad1400 and the display 1600. The processing device 1800 controls theoperation of the display 1600, as well as the overall operation of themobile device 1000, in response to actuation of keys on the keypad 1400by the user. In some embodiments, keypad 1400 may comprise a physicalkeypad or a virtual keypad (e.g., using a touch-sensitive interface) orboth.

The housing 1200 may be elongated vertically, or may take on other sizesand shapes (including clamshell housing structures). The keypad 1400 mayinclude a mode selection key, or other hardware or software forswitching between text entry and telephony entry.

In addition to the processing device 1800, other parts of the mobiledevice 1000 are shown schematically in FIG. 8. These include acommunications subsystem 1001; a short-range communications subsystem1020; the keypad 1400 and the display 1600, along with otherinput/output devices 1060, 1080, 1100 and 1120; as well as memorydevices 1160, 1180 and various other device subsystems 1201. The mobiledevice 1000 may comprise a two-way RF communications device having voiceand data communications capabilities. In addition, the mobile device1000 may have the capability to communicate with other computer systemsvia the Internet.

Operating system software executed by the processing device 1800 may bestored in a persistent store, such as the flash memory 1160, but may bestored in other types of memory devices, such as a read only memory(ROM) or similar storage element. In addition, system software, specificdevice applications, or parts thereof, may be temporarily loaded into avolatile store, such as the random access memory (RAM) 1180.Communications signals received by the mobile device may also be storedin the RAM 1180.

The processing device 1800, in addition to its operating systemfunctions, enables execution of software applications 1300A-1300N on thedevice 1000. A predetermined set of applications that control basicdevice operations, such as data and voice communications 1300A and1300B, may be installed on the device 1000 during manufacture. Inaddition, a personal information manager (PIM) application may beinstalled during manufacture. The PIM may be capable of organizing andmanaging data items, such as e-mail, calendar events, voice mails,appointments, and task items. The PIM application may also be capable ofsending and receiving data items via a wireless network 1401. The PIMdata items may be seamlessly integrated, synchronized and updated viathe wireless network 1401 with the device user's corresponding dataitems stored or associated with a host computer system.

Communication functions, including data and voice communications, areperformed through the communications subsystem 1001, and possiblythrough the short-range communications subsystem. The communicationssubsystem 1001 includes a receiver 1500, a transmitter 1520, and one ormore antennas 1540 and 1560. In addition, the communications subsystem1001 also includes a processing module, such as a digital signalprocessor (DSP) 1580, and local oscillators (LOs) 1601. The specificdesign and implementation of the communications subsystem 1001 isdependent upon the communications network in which the mobile device1000 is intended to operate. For example, a mobile device 1000 mayinclude a communications subsystem 1001 designed to operate with theMobitex™, Data TAC™ or General Packet Radio Service (GPRS) mobile datacommunications networks, and also designed to operate with any of avariety of voice communications networks, such as AMPS, TDMA, CDMA,WCDMA, PCS, GSM, EDGE, etc. Other types of data and voice networks, bothseparate and integrated, may also be utilized with the mobile device1000. The mobile device 1000 may also be compliant with othercommunications standards such as 3GSM, 3G, UMTS, 4G, etc.

Network access requirements vary depending upon the type ofcommunication system. For example, in the Mobitex and DataTAC networks,mobile devices are registered on the network using a unique personalidentification number or PIN associated with each device. In GPRSnetworks, however, network access is associated with a subscriber oruser of a device. A GPRS device therefore utilizes a subscriber identitymodule, commonly referred to as a SIM card, in order to operate on aGPRS network.

When required network registration or activation procedures have beencompleted, the mobile device 1000 may send and receive communicationssignals over the communication network 1401. Signals received from thecommunications network 1401 by the antenna 1540 are routed to thereceiver 1500, which provides for signal amplification, frequency downconversion, filtering, channel selection, etc., and may also provideanalog to digital conversion. Analog-to-digital conversion of thereceived signal allows the DSP 1580 to perform more complexcommunications functions, such as demodulation and decoding. In asimilar manner, signals to be transmitted to the network 1401 areprocessed (e.g. modulated and encoded) by the DSP 1580 and are thenprovided to the transmitter 1520 for digital to analog conversion,frequency up conversion, filtering, amplification and transmission tothe communication network 1401 (or networks) via the antenna 1560.

In addition to processing communications signals, the DSP 1580 providesfor control of the receiver 1500 and the transmitter 1520. For example,gains applied to communications signals in the receiver 1500 andtransmitter 1520 may be adaptively controlled through automatic gaincontrol algorithms implemented in the DSP 1580.

In a data communications mode, a received signal, such as a text messageor web page download, is processed by the communications subsystem 1001and is input to the processing device 1800. The received signal is thenfurther processed by the processing device 1800 for an output to thedisplay 1600, or alternatively to some other auxiliary I/O device 1060.A device user may also compose data items, such as e-mail messages,using the keypad 1400 and/or some other auxiliary I/O device 1060, suchas a touchpad, a rocker switch, a thumb-wheel, track ball, or some othertype of input device. The composed data items may then be transmittedover the communications network 1401 via the communications subsystem1001.

In a voice communications mode, overall operation of the device issubstantially similar to the data communications mode, except thatreceived signals are output to a speaker 1100, and signals fortransmission are generated by a microphone 1120. Alternative voice oraudio I/O subsystems, such as a voice message recording subsystem, mayalso be implemented on the device 1000. In addition, the display 1600may also be utilized in voice communications mode, for example todisplay the identity of a calling party, the duration of a voice call,or other voice call related information.

The short-range communications subsystem enables communication betweenthe mobile device 1000 and other proximate systems or devices, whichneed not necessarily be similar devices. For example, the short-rangecommunications subsystem may include an infrared device and associatedcircuits and components, or a Bluetooth™ communications module toprovide for communication with similarly-enabled systems and devices
